HSBC UK said on Tuesday some of its customers struggled to access online banking, the second outage of the lender’s digital services in weeks, Reuters reported.
“We are investigating further and will provide further updates,” the bank said on Twitter after a number of customers used the social media platform to flag problems accessing HSBC’s site.
The bank’s mobile banking app suffered a brief IT glitch in September, one of a series of outages at Britain’s biggest lenders in the past few months.
Technical problems at European banks have prompted criticism from customers and from lawmakers. Lawmakers in September called on Royal Bank of Scotland (RBS) and Barclays to explain what caused the problems and how they would compensate affected customers.
Outages can cause significant disruption to customers, who are increasingly reliant on digital services as banks close branches and encourage clients to move online.
The impact of a severe outage was brought into sharp focus earlier this year, when mid-sized lender TSB was plunged into chaos after a botched IT migration saw some customers locked out of their accounts for over a week. TSB CEO Paul Pester resigned later.
